[petsc-users] Question about error

[김성익]

Hello,


There are different results from different commands.
However, it should be computed same result between different commands.

The first command is just as below
'./app' (app is my petsc application)
and the results are as below.

And the second command is just as below
'mpiexec -n 1 ./app'
and I got the result what I want.

Actually first of all, I suspected my a1.c:195. However there is no error.
How can I fix this problem??
I don't know where to start.
We continue to investigate from the input data to the structure, but we are
unable to find any suspicious parts.

Thanks,
Hyung Kim
